This exam uses low-dose x-rays to make a picture of breast tissue. The picture is called a mammogram.
Most medical organizations in the United States and Canada advise regular screening. There are some differences among these groups about when to start and how often to have the screenings. The United States Preventive Services Task Force (USPSTF) advises that women aged 50 to 74 years old get the test every two years. Other organizations advise screening every year starting at age 40. Women who are at high risk for breast cancer may need to have the tests starting at an earlier age and more often. Talk to your doctor about what is best for you.
Problems from the test are rare, but all procedures have some risk. Mammograms use low dose radiation and can cause brief pain in the breasts.
The test may not be advised if you are pregnant. If you are planning to have this test, your doctor will go over potential problems with you.
